6..5 grendel

skyfish

Does anyone have any experience on this round. I have a couple questions.

Who manufactures these now? Will they work on any AR-15 lower.
Who makes the ammo?
Seems like it would be easy to reload. But does anyone make brass?
Also, do standard mags work, pmags.

Thanks

skyfish,

Glad you asked. Yes, I do.

1. Alexander Arms and a few builders such as Satern and I think Whitley(who also builds the 6mm AR and 6/6.5mm AR turbo). You could contact Alexander Arms and they have a list of builders they authorize to use the 6.5 Grendel/Alexander Arms names.

2. Any upper built for a 6.5 Grendel will fit on a -15 lower (not a -10)

3. Alexander Arms and Wolf Gold are the two brands of ammo you can purchase. I believe Lapua does the ammo for AA and Prvi Partisan does the ammo for Wolf.

4. A. Lapua and Wolf both make brass. However, Lapua is small rifle and Wolf is Large rifle. Make sure you follow the right guidelines to reload on the Alexander Arms website if you get one.
B. You can form brass from either PPC calibers or from 7.62x39mm brass from which it is all based.


5. Standard mags work but not very well. If you look at the side of the standard .223/5.56mm mag you will see two smaller ribs toward the rear and one larger rib towards the front. On a Grendel mag the rear two ribs are not as deep and they are spaced closer and more toward the rear of the mag so that they guide the body of the bullet forward. If you used standard mags the body/shoulder of the 6.5 case would catch on the forwardmost of the smaller ribs. Also, the larger rib for the .223 is not needed for the wider 6.5mm. It would push the bullet in the case across the feed ramp instead of into the feed ramp.


I have load and ballistic information as well.

Thanks, I didn't know it was formed from the 7.62x39. That seems like a nice little round. I like the fact that it is a AR-15 based round, and I(IMO) think its more usefull than the 6.8spc.

Ballistically it is pretty much a 6.5x55 or .260 Rem.

heres a question. the 260 rem is a necked down 308 correct? would it be possible to just swap out the barrel on any 308 rifle and now have a 260? how about on semi auto rifles(ar-10, m14. fals,hk,cetme)

He Dog,

It is in reality a much smaller round than the 6.5x55 or .260 Rem. It has a max capacity of about 35 gr. full to the brim of water vs. the 51-55 gr. of the .260 and 6.5x55. The 6.5 Grendel produces much less potential with very heavy for caliber bullets.

Joshmb1982,

That should be a separate topic (so you can get a few more answers). But for the most part yes swapping out a .260 barrel for a .308 barrel is a straight across exchange. Edit: the mechanicals of how to do it are different for each rifle type. You really should ask this as it's own topic.[;)]

Interesting Sandwarrior Thanks! The ballistics I looked at in thinking about it, seemed pretty much the same in terms of velocity and energy.

In many cases yes a barrel change or rechamber is needed to go from .308 to .260, or as I did on a bolt action, from .243 to .260. With some it will not be quite that easy.
